STOVE ASH-SIFTER.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed April 27, 1908. Serial No. 429,351.

To all whom it may concern:

Be it known that I, Gusrnv Nos'rwiox, a subjectof the King of Norway` residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvement-s in a Stove Ash-Sifter, of which the following is a specification.

.T his invention relates to improvements in ash sifters for stoves, furnaces and heaters, and it consists in certain peculiarities of the construction, novel arrangement, and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.l

The principal object ofthe invention is to provide an ash-sifter t'o be used in connection with the grates of stoves or other'ire pots for separating the coal from the ashes and for holding the former in a removable receptacle.

' -Another object of the invention is to provide an ash-sifter of the above-named character, which shall be simple and inexpensive in construction, strong, durable and effective in operation, and so made as'4 to combine a horizontally movable grate or a rotary mechanism of the grate with a reciprocating sieve or screen for sifting the ashes and for retaining the pieces of coal.

Other objects and advantages of the invention will be disclosed in the subjoined description and explanation.

In order to enable others skilled in the art to which my invention pertains, to make and use the same, I will now proceed to describe it, referring to the accompanying drawing, in which- Figure 1 is a plan sectional view of a stove provided with a duplex dumping grate and equipped with an ash-sifter, embo ying one form of the invention; Fig. 2 is a vertical sectional view taken on line 2 2 of Fig. 1 looking in the direction indicated by the arrows, showing by -dotted lines the positions to which the dumping grate members mayv be turned and the movement of the ashsifter;-and Fig. 3 is a view partly in section and partly in elevation of a portion of a grate of a lire-box or pot, showing a modi- `fication in the construction of the ash-sifterframe and in the manner 'of .connecting it to a horizontally movable grate.

Like numerals of reference, refer to corresponding parts throughout the diderent views of the drawing. 1

cated in pairs on each side of the stove.

stove or furnace casing, which may be of any desired size, form and material, and, as

usual, has in its lower portion an ash pit 6 which may be equipped with a. door for access thereto. Supported in any suitable manner within the casing 5 and at the upper portion of the-ash pit 6 is a stationary grate or fire-pot 7, which, in the present instance, is shown as being circular and downwardly and inwardly extended. The lower portion of the stationary grate or fire-pot 7 is pro` vided at suitable distances apart with. in-

wardly extending horizontal projections 8 on which is movably mounted a circular grate 9 which is provided at its front portion with an extension 10 which projects-through a suitable opening in the stove or furnace casing 5, and may be used for shaking the grate 9 by a horizontal movement of said extension. Located within the central opening of the circular grate 9 are twodumping grate members 11 and 112L which are substantially semi-circular in shape, and each has on its rear portion a shaft 12 which shafts are j ournaled attheir outer ends in the casing 5, and each has mounted thereon a gear 13 Each of the members 11 and 11 is provided on its front portion with horizontally extending shafts 14 which are journaledin the front part of the `stove casing, and one of said shafts has shake the coal and ashes therefrom. At'

about its middle, one of the dumping grate members is provided with a downwardly extending arm 16 to which is pivotally secured at one of its endsa rod or bar 17, the other end of. which is pivotally secured to an upward extension or arm 18 on the sifterframe 19, which is supported within the ash pitrby-means to be presently explained.

As shown in Figsl and 2 of the drawing, the lower portion of the grate 7 is provided on its outer surface with a series of bosses or projections 20usuall`y four in number, `lo- Pivotally secured to each of the projections 29 is a link 21, the other end of each of which is 'pivotally secured to an arm 22 on the upper portion of the sides of the sifter-frame19,4 which, as shown, is preferably rectangular in shape, and has at its bottom a perimetral and inwardly extending flange 23 to supportl f the ash-sifter 24, which is also preferably rectangular in shape andofa form to correspond with that of the' frame 19, and has its bottom provided with a series of perfo- 'rations 25 through which the ashes may be sift/ed so/ as to fall on the floor of the ash pit.

' /InvFig 3 ofthe drawing I have shown a modification in Vthe construction of .the device/and in said ligure have illustrated a ,/si/ft'r-rame connected to a reciprocal grate, lO/instead of to one of the dumping or rotary "'type. In this modification,` the stationary .grate 7 of the stove or furnace is provided,

` as in the other construction, with a number of projections 20, to each of which is pivotally secured atone of its ends a link 21, the other ends of which are similarly secured to arms 22 on the upper surface of the sifterframe 19, which is of the same construction as that shownin Fig.' 2 and just above-de-v .25' stood that, when the construction shown in Figs. 1 and 2 is employed, the circular grate 9 may be turned by means of the extension -10 so as to shake the same, and that the dumping grate members 11 and-11a may be rocked by means of a crank appliedto the 'end 15' of the shaft 14, thus causing thel ashes and-small portions of coal to fall into the sifter 24, which, as well as the frame 19 therefor, will be vreciprocated by the movement 'of the dumping grate members, by

' reason ,of the connections 16, 17 and 18, which unite one of said grate members and the siiter-frame. l

` -It is apparent that,'wl1n the construction 40 shown in Fig. 3 is employed, the grate 26, which may be horizontally supported in any -suitable manner so that it can be moved horizontally,l will, in its movement, cause the sitter-frame 19 to be reciprocated through the instrumentality of the connecting rod 17 a and arms 16a-and 18a to which said rod is pivotally connected at its ends.

' 'F rom the foregoing it will be understood that an ash-siftcr of an extremely simple and practicable nature is afforded by my improv'ements, and that the invention is susceptible of considerable modication without material departure from the principles and spiritof the invention, and for this rea- 55. sonl I do not desire to be understood as limitingl myself to the precise form and arrangement of the several practice.

1. The combination with the casing of a stove or the like, of a grate movably located therein, a sifter-frame of a bottomless boxlike form having at its lower portion inwardly extending flanges and movably supported below the grate for reciprocal movement, a sifter of corresponding shape to the frame removably located therein and supported on said flanges, and means connecting the sitter-frame to the grate whereby when the latter is movedreciprocating movement will be imparted to the sifter-frame.

2. The combination with the casing of a stove or the like, of a stationary grate located therein, another grate movably located within the casing, a sifter-frame of a bottomless box-like `form having at its lower portion inwardly extending flanges, a series of links vpivotally uniting the stationary grate and the sitter-frame, a rod pivotally connected at one of its ends to the movable grate and at its other end to the sitter-frame, and a sifter of corresponding shape to the said frame and removably located therein and supported on the flanges thereof.

3. The combination with'the casing of a stove or the like,- of a stationary grate rlocated therein and having a central opening, a

movable grate located within the casing and 4central opening of the stationaryI grate, a

sifter-frame of a bottomless box-like form having at its lower portion inwardly extending flanges, a series'of links pivotally secured at their endsl to the stationary. grate and to the sifter-frame, a rod pivotally connected at one of its ends to the movable grate and at its other end to the sifter-frame, and a sifter removably located in the frame therefor and supported on the flanges thereof.

4:. The combination ,with .the casing of a stove or the like, of a grateconsisting of two rotary members horizontally mounted therein and having means to operatively unite them, a sifter-frame of a bottomless box-like form having at its lower portion inwardly extending flanges and movably supported below the grate, a sifter removably located in the sitter-frame .and supported on .the flanges thereof,l and means connecting the sitter-frame to one of'the'grate members whereby when the latter is moved reciprocating movement will be impartedvto thel said frame.
